J. O. WELLS. GONG BELL.

Patented June 6, 1898.

UNITED STATES PATENT OFFICE.

JOHN C. WELLS, OF EAST HAMPTON, CONNECTICUT, ASSIGNOR TO THE BEVIN BROTHERS MANUFACTURING COMPANY, OF SAME PLACE.

GONG-BELL.

SPECIFICATION forming part of Letters Patent No. 498,908, dated June 6, 1893.

Application filed March 1, 1893.

To ctZZ whom it may concern:

Be it known that I, JOHN C. WELLS, of East Hampton, in the county of Middlesex and State of Connecticut, have invented certain new and useful Improvements in Gong-Bells, of which the following is a full, clear, and exact description, whereby any one skilled in the art can make and use the same.

The object of my invention is to provide a gong bell that shall be simple and cheap in construction While combining the shape, ap-

pearance and effectiveness of a bell of more expensive make, and a further object is to provide a bell in which the hammer shall make a double blow with the one swinging movement of the lever on which itis mounted, such a bell being particularly adapted for use on bicycles and like vehicles as an alarm bell.

To this end my invention consists in the details of the several parts of the bell and in the combination of such parts as more particularly hereinafter described and pointed out in the claims.

Referring to the drawings: Figure l is a detail plan view of the interior of the bell showing the base piece with the parts connected thereto. Fig. 2 is a detail interior View of the base piece and the parts mounted thereon shown with the carrier arm swung forward. Fig. 3 is a detail view in section of the bell showing the outline of a gong and base piece with the hammer and supporting parts partly broken away. Fig. 4 is a detail view on enlarged scale of the hammer mount. Fig. 5 is a detail View on enlarged scale of a modified form of the hammer mount.

In the accompanying drawings the letter Ct denotes the base piece of a gong bell preferably made of metal in the form shown and either cast or spun to shape. A post I) fixed in the center of the base piece supports the gong c which may be secured to the post as by means of ascrew thread thereon, entering a socket in a lug on the under surface of the gong, but the several means of securing these parts or of mounting the parts on the base are not material to the invention. To the base piece a is pivoted a carrier arm 01 preferably extending completely across the base piece and of such shape as to enable it to be given a swinging movement without being obstructed by Serial No. 464,154. (No model.)

any of the partswithin the bell. The outer end of this carrier arm which extends through a slot or like guide a is preferably made broad and of a proper size and in the proper position to present a surface against which the thumb of an operator may be pressed in swinging the carrier arm. On this carrier arm is supported a hammer mount f which is pivoted to the carrier arm near its outer end and in one form comprises a forked tumbler g, the arms g g of which extend on opposite sides of a stop It fixed to the base piece and the stop h, arranged so that as the carrier arm d is swung on its pivot, an arm gstrikes against the stop it and causes the tumbler to turn carrying with it the hammer t' that is secured to the tumbler by any suitable tongue 2'.

A spring 7c preferably of V-shape with one or more central coils k to add to its resiliency is attached at one end k to a pin or post Zfast to the base piece, preferably near the outer edge and beyond the plane of movement of the outer end of the carrier arm so that the latter in its movement toward this fixed point will cause the spring, the end 70 of which is connected to the tumbler g, to be compressed. The point of pivotal connection of this spring to the tumbler is so arranged that as the lever handle is swung forward the pivot g to which the spring is connected will be drawn forward toward a line drawn between the post Z and the pivot g on which the tumbler turns until on passing the center the recoilof the spring thrusts the tumblersharply around throwing the arm 9 into contact with the stop h, the hammer by this means being thrown into contact with the wall of the gong causing it to sound. As soon as pressure upon the thumb piece on the outer end of the carrier arm is withdrawn the recoil of the spring throws the carrier arm back and swings the tumbler in an opposite direction to the movement of the carrier arm until the arm g is brought sharply into contact with the stop It and causes the other end of the hammer to strike in its second position sharply against the wall of the gong causing it to sound.

It will be seen that the swinging movement of the forked tumbler is caused by the swing ing movement imparted to the carrier arm against the pressure of the spring and also by the recoil of the spring, the hammer striking a sharp blow at each end of its swinging movement, a single swinging movement of the carrier arm causing the two blows to be struck.

In the modified form of the hammer mount shown in Fig. 5 of the drawings instead of a forked tumbler the arms of which engage the fixed stop on the base piece the tumbler arm is single and is adapted to make contact with the two fixed stops formed by the downturned arms of the loop h that is secured to the base piece, this forming an equivalent means of operating the hammer to that already described.

I claim as my invention- 1. In a gong bell in combination with a base piece, a swinging carrier arm pivoted to the base piece, a thumb piece on the arm located beyond the edge of the base piece, a hammer mount pivoted to the carrier arm,a stop fixed to the base piece and limiting the swinging movement of the hammer by contact with a projecting part of the hammer mount, and a spring normally holding both the carrier arm and the hammer mount at one limit of their play, all substantially as described.

2. In combination in a gong bell, a base piece, a gong supported thereon, a swinging carrier arm pivoted to the base piece and having a handle extending beyond the base piece, a tumbler carrying a hammer and pivotally supported on the carrier arm, a stop fixed in the path of movement of the tumbler arm, and a bent spring fastened at one end to the base piece and at the other to the tumbler and normally holding both the carrier arm and the hammer mount at one limit of their swinging play, all substantially as described.

3. In combination in a gong bell, a base piece, a gong supported thereon, a swinging carrier arm pivoted to the base piece and having a handle extending beyond the base piece through a guide slot, a tumbler carrying a hammer and pivotally supported on the carrier arm with projecting arms extending on both sides of a fixed stop, a stop fixed in the path of movement of the tumbler arm and the bent spring having a number of coils at its angle and fastened at one end to the base piece and at the other to a pivot on the tumbler arm the latter being located normally at one side of a line drawn from the center of the spring support on the base piece to the center of the tumbler pivot, all substantially as described.

4. In combination in a gong bell, a base piece, a gong supported on a central post thereon, a swinging carrier arm pivoted to the base piece and extending through aslot therein the outer end of the arm being turned and broadened to form a handle located beyond the limits of the base piece, a tumbler 'mount carrying a hammer and pivotally supported on the carrier arm, a stop fixed in the path of movement of the tumbler arm, and a bent spring fastened at one end to the base piece and at the other to the tumbler and normally holding both the carrier arm and hammer mount at one limit of their play, all substantially as described.
